Figure 4-11 Fast Path configuration and monitoring Fast Path has two Spanning Tree Protocol configuration options: • Enabled or disabled, as discussed in the previous section • Spanning Tree Protocol (STP) type Both of these settings are located on the Advanced Redundancy tab in NCU. Refer to Figure 4-11. There are two predominate Spanning Tree Protocols (STP) in use today. They are IEEE 802.1D Spanning Tree Protocol and Cisco® Per VLAN Spanning Tree Plus (PVST+) Protocol. The Fast Path implementer should choose which version of Spanning Tree is in use on the attached network. If IEEE 802.1D is chosen under the Fast Path configuration section, the teaming driver configures the teamed ports to listen for IEEE 802.1D BPDUs. This involves registering, in hardware, a specific multicast MAC address (01-80-C2-00-00-00) on all teamed ports and monitoring for Spanning Tree frames in the IEEE 802.1D frame format. Since the IEEE 802.1D STP is VLAN unaware, it is not necessary to configure the VLAN for Fast Path to listen to. If Cisco PVST+ is chosen under the Fast Path configuration section, the teaming driver configures the teamed ports to listen for Cisco PVST+ BPDUs. This involves registering, in hardware, a specific multicast MAC address (01-00-0C-CC-CC-CD) on all teamed ports and monitoring for Spanning Tree frames in Cisco PVST+ frame format. Since Cisco PVST+ is VLAN aware, configuring the VLAN for PVST+ to monitor may be necessary. By default, Fast Path using Cisco PVST+ will monitor the first VLAN configured on the team. The VLAN monitored by Fast Path can be changed on the VLAN configuration tab in NCU.

Figure 4-11 Fast Path configuration and monitoring
Fast Path has two Spanning Tree Protocol configuration options:
•
Enabled or disabled, as discussed in the previous section
•
Spanning Tree Protocol (STP) type
Both of these settings are located on the Advanced Redundancy tab in NCU. Refer to
Figure 4-11
.
There are two predominate Spanning Tree Protocols (STP) in use today. They are IEEE 802.1D
Spanning Tree Protocol and Cisco® Per VLAN Spanning Tree Plus (PVST+) Protocol. The Fast
Path implementer should choose which version of Spanning Tree is in use on the attached
network.
If IEEE 802.1D is chosen under the Fast Path configuration section, the teaming driver configures
the teamed ports to listen for IEEE 802.1D BPDUs. This involves registering, in hardware, a
specific multicast MAC address (01-80-C2-00-00-00) on all teamed ports and monitoring for
Spanning Tree frames in the IEEE 802.1D frame format. Since the IEEE 802.1D STP is VLAN
unaware, it is not necessary to configure the VLAN for Fast Path to listen to.
If Cisco PVST+ is chosen under the Fast Path configuration section, the teaming driver configures
the teamed ports to listen for Cisco PVST+ BPDUs. This involves registering, in hardware, a
specific multicast MAC address (01-00-0C-CC-CC-CD) on all teamed ports and monitoring for
Spanning Tree frames in Cisco PVST+ frame format. Since Cisco PVST+ is VLAN aware,
configuring the VLAN for PVST+ to monitor may be necessary. By default, Fast Path using Cisco
PVST+ will monitor the first VLAN configured on the team. The VLAN monitored by Fast Path
can be changed on the VLAN configuration tab in NCU.
